摘　　要：在分析了矿体及围岩稳定性的基础上 ,提出了报废采场残留矿体的回收方法 ,在完成采场残留矿体的回采工作中 ,以低廉的成本回收了残留高品位矿石 ,扭转了三级保有矿量不足的被动局面。经过实践证明 ,该方法是一种行之有效的方法。The stability of orebady and its surrounding rock is analysed, on this basis, the ways to recover remnant ore in empty stope are put forward. In stoping of remnant ore in the empty stope, high grade remnant ore is recovered at low cost, putting an end to the passive state of unadequate Level-3 reserved ore tonnage. It has been shown that the method is effective in practice.
